Found this clip of Mohamed Matar playing Besh el-Ghawazi
Mohamed Matar is a Lebanese master of the bouzok instrument. His style is close to Gypsy music, and this piece, as the title suggests, is performed by the Ghawazi (Gypsy) dancers from the Ghajar (or Nawar) clans living in Lebanon and other countries of the Middle East. The Ghawazi usually perform in wedding feasts, singing mostly erotic and crude song
